Build custom extensions that plug directly into Vision overlays. You write React, Vision handles rendering, storage, and real-time sync between your settings panel and the stream overlay. Need a backend? Add server functions to get a per-install edge database with typed queries, mutations, and actions.

What You Can Build

Extensions are custom layer types that streamers add to their overlays. A single extension can have up to three parts, plus an optional server backend: All three UI parts share the same storage. Change a value in the editor panel and the layer updates on stream instantly. Server functions give you a separate per-install database for structured data that goes beyond key-value storage. Use the interactive/control-panel surface for participant controls and session workflows. It is not intended to host high-scale public pages for thousands of concurrent viewers.

How It Works

You write standard React using SDK components for the UI, and TypeScript functions for the backend. The SDK takes care of the rest:
This renders a toggle in the overlay editor. When the streamer flips it, storage.visible updates and the OBS layer re-renders immediately — no extra wiring needed.
You don’t need to set up websockets, databases, or state management. The SDK handles persistence and real-time sync out of the box.

Requirements

  • Node.js 18+ and a package manager (pnpm, npm, or yarn)
  • A Vision account at app.1up.vision
  • Basic knowledge of React and TypeScript
